The expression is equivalent to 12 minus 3 + 7 because of the commutative property.
The expression is equivalent to 12 + 3 + (negative 7) because of the commutative property.

c. The expression is equivalent to 12 minus 3 + 7 because of the commutative property.

Step-by-step explanation:

The communitive property ensures that whatever the order (in addition and multiplication) the answer is the same.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
